How do Music and Science go together?
The Vibration Song sung by Dorothy Collins
An old man lives in a house in a neighborhood full of many families of all ages. On his street there
are often young children yelling, small dogs barking, bicycles ringing their bells as they pass by and a rock band that rehearses in their garage. Every day the old man walks down through the noisy street to the rock band and tells them to "BE QUIET!" There are many reasons why he could be singling out the band to be quiet, but in this story there is in fact only main reason. Look at the map of the street and see if you can figure out why he only yells at the rock band to be quiet each day.

What is the dangerous aspect of the relationship
between SOUND WAVES
and your EARS?
TUNING FORK
There are many different sizes for tuning forks.
I have a tuning fork marked C256. That means that when I strike the tuning fork, it vibrates 256 times per second! When something vibrates at 256 times per second, it creates the note C.
PITCH
The faster the waves travel, the higher the pitch will be
Example of a two pitchesThe top pitch is high, the bottom pitch is low
A pitch will be high or low depending on the size of the object creating the soundThe smaller an object is, the faster vibratesThe larger an object is, the slower it vibrates
Relating this concept to musical instruments
A pitch will be high or low depending on the size of the object creating the sound
The smaller an object is, the faster vibratesThe larger an object is, the slower it vibrates
Large Boomwhackers vibrate slowly and create a low pitch. Small Boomwhackers vibrate quickly and create a high pitch.

To Review:
The Frequency of a wave determines the Pitch of a sound (how low or high the sound is)
The Amplitude of a wave determines the Volume of a sound (how quiet or loud the sound is)
Match the red and blue words to their sound waves

Sound travels in waves. Can you match the sound waves with WORDS and PICTURES?
